A novel small and compact flexible monopole antenna for UWB applications

Abstract

A novel small flexible elliptical monopole antenna on the basis of the disk monopole antenna structure is presented and developed in this paper. The improved antenna reduces the height and can realize good bandwidth performance; it has low cost, simple structure, and flexible characteristics. The novel elliptical antenna was bent on a cylindrical surface which once more reduces the space in term of larger of the antenna; good performances were achieved compared to flat elliptical one: a directional radiation pattern at all frequencies band and an increasing gain were obtained. The impedance bandwidth, radiation pattern and peak gain, of the antennas, are studied and presented, they have been investigated using simulation software CST and experimental results. The measured and simulated results showed excellent agreement. The novel small elliptical monopole antennas will be suitable for UWB applications.
